The idea of handing out lecture notes in advance, thus allowing class time to be used more creatively, is indeed appealing. However, I clearly remember the classes where I learned the most in college. They were not like that at all. Rather, the professor wrote almost an entire textbook on the blackboard, which I dutifully transcribed. The simultaneous engagement of eye, hand, and brain was somehow engrossing. I cherished these notes and inscribed them on my memory. Now, when I teach, I meticulously prepare notes for myself but don't hand out copies. It is up to students to write their own editions, so to speak. This seems old-school, but I've found that it works. To be sure, the pace mustn't be so fast that students become mere stenographers. They need time to think things over. And care is needed to distinguish the essential from the more trifling (often simply by repeating the former a few times). While it isn't and shouldn't be the only way to teach, I feel there is a place for a more formal lecturing style alongside the exciting, freewheeling approach advocated by Prof. Tao.
